Temporal and angular profiles of backscattered pulses are introduced as a viable, novel and noninvasive technique to probe biological and medical materials. The optical properties of these materia's are quantitatively measured in terms of two scattering length scales the transport mean free path and the absorption length of the light. We show that these two scattering lengths can be directly determined from an analysis of the temporal and/or the angular profile of the backscattered pulse intensity. Weak localization of the photon are observed in the tissues. Experimental results for transient light backscattering from the human eye, normal and cancer lung and breast tissues, and tooth; from chicken heart; and leaf are presented.
